As the first step of this research project on the development of artificial lighting system for producing quality transplants, an experimental artificial lighting system was developed. The light source of artificial lighting system was consisted of blue, green and red light emitting diodes. The light output of blue, green and red light emitting diodes could be modified by manual. Using this system, the effect of blue, green and red light ratios on the growth and development of tomato seedling was investigated. A significant effect of light energy composition on the growth and development was found. Secondaly, an experiment on quality preservation of transplants during the low temperature storage was conducted. The experiment showed that the quality was better preserved under dim light than under darkness. Thirdly, the cost of electricity for lighting and air conditioning during the transplant production was estimated to be about 2 Yen/transplant. This results shows that the transplant production under artificial light can be commercialized. Experiments on carbon dioxide enrichment for sweetpotato transplant prduction, transpirational and photosynthetic characteristics of sweetpotato cuttings were conducted and fruitful results were obtained.

作为开发用于生产优质移植物的人工照明系统的研究项目的第一步，开发了一种实验性的人工照明系统。人工照明系统的光源由蓝、绿、红三种发光二极管组成。蓝、绿、红三种发光二极管的光输出均可手动修改。利用该系统研究了蓝、绿、红光比对番茄幼苗生长发育的影响。光能组成对其生长发育有显著影响。其次，进行了移栽在低温贮藏过程中的品质保鲜试验。实验表明，在暗光条件下比在黑暗条件下保鲜效果更好。第三，移植生产期间照明和空调的电费估计约为2日元/移植。这一结果表明，人工光照下的移栽生产是可以商业化的。对甘薯插穗移栽生产、蒸腾和光合作用特性进行了增施二氧化碳的试验，取得了丰硕的成果。
